JVM Auto Shutdown

Hi All,

I have been searching for similar issues on web and also here but couldnt find anything yet. I am so sorry if this is a naive question but here it goes:

I have jar file which I need to keep it running all the time as it is an RMI server. But the problem is, after some time - randomly - jvm shuts itself down and i cant use my server any more.

I am just curious if i am missing any points or is there any way to prevent jvm acting like that?

thank you in advance

p.s i am using java7u2
